Honey can be extracted from honeycomb that is packed in a filter cloth and squeezed under high pressure by means of a screw mechanism or other means of generating a large thrust.
Many different methods can be devised to achieve this by simple means and small or large scales as may be appropriate to the amount of honey that is to be extracted in this fashion.
Honey can be extracted by this method for two main reasons, as a means of dealing with thixotropic honeys like those derived from heather nectar, or any type of honey that is being extracted on a small scale.
The large scale requires a large and massively strong press. The principle of this pressing through a cloth can be incorporated at a smaller scale by using a wine press or by constructing a heavy duty frame and applying pressure by means of a car jack.

These two types both have central threaded pillars, in the case of the first one this thread is wound down through a nut that is welded to the frame, but in the case of the other one the thread is fixed and the pressure is applied by winding a nut down it using a ratchet mechanism, the thrust being transferred by a tube around the lower part of the thread. Either one of these two will produce great results.
